Yeast Infection During Pregnancy: Symptoms & Treatment

Updated in February 2024

A yeast infection during pregnancy is a very common situation among pregnant women. During this period, estrogen levels are higher, favoring the growth of fungi, especially Candida albicans, which in naturally found in the woman's vagina.

Yeast infections during pregnancy do not harm the baby, but if the baby is born vaginally and the woman has an active yeast infection, the baby may be infected and present with a yeast infection in its first days of life.

If the baby is infected, he or she may present whitish plaques inside the mouth, also known as thrush, and when breastfeeding he or she may transmit the fungus again to the mother, who may develop a breast fungal infection. This can make the initiation of breastfeeding difficult.
